It is interesting how I have got a friend who once commented that all forms of market failure is a result of imperfect information. He says that people are consuming too much or too little of a product because they don't have perfect information about the impact of the products, and so basically all the inability to analyse cost and benefit is a result of imperfect information. Likewise, to this friend of mine, technological advancement is basically slowly discovering information, truths that we previously know nothing of. Of course, that's a little extreme and basically demanding perfect knowledge as well. For him, perfect knowledge would naturally be attained from having sufficient information.
The digital age ushered in lots of information; so much that we don't have enough time to process them. In fact, even cataloguing them might be troublesome enough and the process generates meta-data, which in fact is information about information. They would prove useful though they actually add to the information heap. Say for example I give you a quote:
The setting sun, and music at the close,
As the last taste of sweets, is sweetest last,
Writ in remembrance more than things long past:
If I don't provide the source, it's not particularly helpful unless you're able to identify it from just the content. It's from Shakespeare's The Tragedy of King Richard the Second. But then that's just a little bit of metadata; there's more: it comes from Act II Scene I. And even more: it's from Line 14-16. The ability to manipulate all these data themselves would create more information too. And they all might just prove to be way too much.
Economics have definitely become more complex thanks to the flood of information. Technology has allowed suppliers to maintain tighter inventory and reduce idle capacity but reality seem to drift further away from classical economics even as the economic agent are becoming more equipped with the information necessary to create a more perfect market. It appears, the next big assumption of Economics about the real world that needs toppling is in fact the idea of independence.
